The overall process of photosynthesis has the balanced chemical equation 6CO, +6H,0 CH.0, 60, What does this tell you about the relative amounts of carbon
dioxide and water consumed in this process?
A. For every six moles of carbon dioxide consumed, one mole of water is consumed
B. For every mole of carbon dioxide consumed, one mole of water is consumed
C. For every gram of carbon dioxide consumed, one gram of water is consumed
D. For every six grams of carbon dioxide consumed, one gram of water is consumed.

Answers

Answer:

(C)

Explanation:

Because of the physics of it.

According to the overall equation of photosynthesis as follows: 6CO2 + 6H2O = C6H12O6 + 6O2, for every mole of carbon dioxide consumed, one mole of water is consumed.

What is photosynthesis?

Photosynthesis is the process by which plants and other photoautotrophs convert light energy into chemical energy.

Photosynthesis makes use of carbon dioxide and water to produce glucose and oxygen as follows:

6CO2 + 6H2O = C6H12O6 + 6O2

This chemical equation suggests that for every mole of carbon dioxide consumed, one mole of water is consumed.

What information does the periodic table give you?

Answers

Hi,
The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.

The periodic table is divided using groups (columns) and periods (rows).

Each specific group or period has a specific pattern in the elements.

The modern periodic table is arranged in order of increasing atomic number.

I’m not really sure what information what you were asking for but I hope this helps..

Hello!
The modern periodic table was created by Dmitri Mendeleev with the main goal of showing rows and columns with a logic arrangement of chemical elements.

In each column, the groups, the elements have the same number of electrons in the outermost shells. While the rows are called periods or series.

How is the momentum of an object determined?
What happens every time one of the boys playing ping pong hits the ball?
How could the boy playing ping pong keep from hitting the ball off the table?
I GIVE 20 PTS PLS HEELP

Answers

Answer: He needs to hit the ball with less force.

Explanation:

hope this helps

1. Momentum = mass x velocity

2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.

3. Momentum before = momentum after
Every time the ball hits the table, some momentum transfers from the ball to the table. Every time the player hits the ball, some momentum transfers from the player to the ball. This allows the player to continue playing ping pong as the ball always has momentum.

How is the stimulus concept currently in our lives? (Ivan Pavlov) in TTQA

Answers

Answer:

stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine. An example of internal stimuli is your vital signs changing due to a change in the body.

As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.

During an investigation, a scientist burned 48 g of magnesium strip. After the reaction, the total mass of the product formed was found to be 80 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations.

Answers

Answer

yes

Explanation:

the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.

Answers

Answer:

As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.

At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.

This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.

Answer:4: Both Air and Oxygen decrease.

Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,
