) has a half-life of 15 hr. if the sample activity is 100 millicuries after 24 hr, approximately what must its original activity have been? b
Answers
Given that the half-life of an element is 15 hours and the sample activity after 24 hours is 100 millicuries, we need to determine the original activity.
Let the original activity of the sample be x millicuries. Now, let us find the fraction of the sample left after 24 hours.Fraction remaining after 24 hours = (1/2)^(24/15) = (1/2)^(8/5) ≈ 0.34We can set up the following equation to solve for x:(1/2)^(8/5)x = 100Multiplying both sides by (1/2)^(8/5),
we get:x = 100/(1/2)^(8/5) ≈ 291.50 millicuriesTherefore, the original activity of the sample was approximately 291.50 millicuries. Hence, the main answer is 291.50 millicuries.The half-life of an element is 15 hours and the sample activity after 24 hours is 100 millicuries. To determine the original activity, we use the formula:(1/2)^(8/5)x = 100. Here, x is the original activity of the sample. After substituting the values, we get x = 100/(1/2)^(8/5) ≈ 291.50 millicuries.

Answers
The equation for the half-reaction is:
Cyanogen + Hydrogen ion + 2 electrons → Hydrogen cyanide
The balanced chemical equation for the given redox reaction is given by:CN2(3-) + 2H+ + 2e- → 2HCNFrom the given balanced equation:
Reactant: CN2(3-) and Product: HCN
In the balanced equation, number of electrons transferred = 2.The standard electrode potential, E° for this half-reaction is equal to 0.59 V.
Therefore, the E' for the given half-reaction can be calculated by using the following formula

a) write a chemical balanced equation
b) calculate the number of theoretical moles of hydrogen that should be reduced in this reaction.
c) calculate the volume of hydrogen gas produced. remember that the gas is collected over water.
d) you now quickly do a burning splint test on the hydrogen. jt reacts with just enough oxygen in the gas collecting tube to produce liquid water. what mass of liquid water is produced? (new balanced equation)
Answers
Answer:
a)Mg(s) + 2HCl(aq) -------> MgCl2(aq) + H2(g)
b) 0.125 moles of hydrogen gas is reduced in the reaction.
C) 3.18 L
d)2.25 g of water
Explanation:
a) the equation of this reaction is;
Mg(s) + 2HCl(aq) -------> MgCl2(aq) + H2(g)
b)
Number of moles= concentration × volume= 1.0 × 250/1000 = 0.25moles of HCl
From the equation;
2 moles of HCl yields 1 mole of hydrogen gas
Hence 0.25 moles of HCl yields 0.25 × 1/2 = 0.125 moles of hydrogen gas
Thus 0.125 moles of hydrogen gas is reduced in the reaction.
c)
P= 760 mmHg (standard pressure)
V= ????
T= 298 K
n= 0.125 moles
R= 0.082 atm dm-3K-1mol-1
Since the gas is collected over water, SVP of hydrogen at 25°c is 28mmHg
Therefore; P=760-28= 732mmHg
But
1 atm =760 mmHg
Therefore 732 mmHg= 732/760= 0.96 atm
PV=nRT
V= nRT/P
V= 0.125 × 0.082 × 298/0.96
V= 3.18 L
Note 1dm-3=1L
d)
2H2(g) + O2(g) ----> 2H2O(g)
From the equation;
2 moles of hydrogen yields 2 moles of water
0.125 moles of hydrogen yields 0.125 moles of water
Mass of water = 0.125 moles × 18gmol-1 = 2.25 g of water

As Potassium have the +1 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Iodide it will be -1, so, the formula will be:
KI
And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:
K⁺ + I⁻ ------> KI
2. Solution 1 and 3, Lead (II) nitrate and Sodium carbonate:
In this case I will work with both, because both of the solution are tertiary compounds. In this cases, we have two tertiary salt, The Sodium symbol is Na, and is working with it oxydation state +1. Carbonate is an anion and have the formula CO₃ working with the oxydation state -2. Lead can work with oxidation state +2 and +4. It's symbol is Pb. Nitrate is NO₃ and works with oxydation state -1 instead.
The chemical formula and ionic equation for both will be:
Lead(II) nitrate: Pb(NO₃)₂
Sodium Carbonate: Na₂CO₃
And the net equations:
Lead nitrate: Pb²⁺ + 2NO₃⁻ ------> Pb(NO₃)₂
Copper sulfate: 2Na⁺ + CO₃²⁻ -------> Na₂CO₃

Flammable liquids are those that have a flashpoint of:.
Answers
Answer:
Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).
Explanation:
:)
Flashpoints for flammable liquids are at 100°F. Lower flash points allow for easier ignition of liquids. A liquid's flash point is the lowest temperature at which a concentrated enough layer of vapor accumulates on top of its surface to allow for ignition.
A liquid that is flammable has a flash point* below 37.8 ° C (100 ° F). A flammable liquid has a flash point that ranges from 37.8 to 93.3° C (100 to 200° F), which is above the standard working temperature. Flammable liquids emit a vapor that, at standard working temperatures, is easily ignitable.
The substance ignites more readily the lower the flash point. For instance, petrol is more flammable than ethylene glycol and has a flash point of about -40 degrees C (-40 °F).

A less stable carbocation can rearrange to a more stable carbocation by shift of a hydrogen atom or an alkyl group. These rearrangements are called ____________ and ____________ shifts, respectively.
Answers
A less stable carbocation can rearrange to a more stable carbocation by shift of a hydrogen atom or an alkyl group. These rearrangements are called hydride and alkyl shifts, respectively.A carbocation is a positively charged species with a vacant p orbital present in the carbon atom.
The vacant p orbital forms a pπ-pπ bond with the nucleophile, while the electrophilic carbon atom is known as a carbocation. It can be formed in a unimolecular reaction in which one bond breaks to form a carbocation and a leaving group.A carbocation can be stabilized by the electron-donating ability of alkyl groups or electron-withdrawing effects of various functional groups. The electron-donating effects of alkyl groups help to stabilize the positive charge. Therefore, as the number of alkyl groups attached to the carbocation's carbon atom rises, so does its stability.The stability of carbocation depends on the number of alkyl groups attached to the carbocation's carbon atom. The greater the number of alkyl groups attached to the carbocation, the more stable it will be. When the carbocation is less stable, it will rearrange to form a more stable carbocation through a shift of a hydrogen atom or an alkyl group. When hydrogen is moved, it is known as a hydride shift, and when an alkyl group is shifted, it is known as an alkyl shift.

However, in general, water molecules form hydrogen bonds with each other due to the polarity of the water molecule. These hydrogen bonds contribute to the unique properties of water, such as its high boiling point and surface tension.
d. The question does not specify the color of the new bonds that form between the solute (NaC₂H₃O₂) and the solvent. The color of the bonds formed between the solute and solvent is not a defining characteristic and can vary depending on the specific context or representation being used.
It is important to note that the given question lacks specific details or context regarding the colors and changes in bonds. Further information or clarification would be necessary to provide a more accurate and detailed response.

What are the two types of adaptations that plants can show? (2 points) a Physical characteristics and life cycle differences. b Life cycle differences and color differences. c Physical characteristics and different food sources. d Physical characteristics and behavioral differences.
Answers
physical characteristics and life cycle differences are the two types of adaptations that plants can show (option A)
What is adaptation?The science community has long recognized adaptation as critical in sustaining living entities' livelihoods worldwide. Organisms gradually evolve by changing specific characteristics susceptible to environmental pressures through natural selection- enabling advantageous features within nature's unique selective pressures compared to less-adapted species when navigating complex environments .
Further categorizing adaptation into three groups provides us insight into how life adapts best – Physical adaptations suitable for warding off potential threats; Behavioral adaptations improving available resources; Physiological adjustments maximizing bodily functions within the context provided by the environment

If a handsaw does the same amount of work on a log is a chainsaw does, which has more power? Why?
Answers
Since both does the same amount of work, don’t worry about the variable W
Let’s talk about t, time
A chainsaw can cut into a log at a faster time than a handsaw can
Let’s assume chainsaw = 2 minutes
A handsaw = 6 minutes
Let’s pretend work = 12
12/2 = 6 power (chainsaw)
12/6 = 2 power (handsaw)
Based on this example, you can see that chainsaw has more power.
