grigory [225]3 years ago
6 0
The procedure for this is the next one:
moles CaC2 = 485 g/64.1 g/mol=7.57 
<span>moles H2O = 2 x 7.57 =15.1 </span>
<span>mass H2O = 15.1 mol x 18.02 g/mol=272.8 g 
</span>

A plate moves 200 m in 10,000 years. What is its rate in cm/year?
Varvara68 [4.7K]

Answer:

The answer is

<h2>2 cm/year</h2>

Explanation:

To find the rate in cm/year we must first convert 200 m into cm

1 m = 100 cm

if 1 m = 100 cm

Then 200 m = 200 × 100 = 20 ,000 cm

So the rate is

<h2>\frac{20000}{10000}</h2>

<u>Reduce the fraction with 10,000</u>

We have the final answer as

<h3>2 cm/year</h3>

Hope this helps you

Alika [10]

Answer:

Check the explanation

Explanation:

Glycolysis is the process in the field of chemistry in which a specific glucose molecule is broken down to become two or more molecules of pyruvic acid or pyruvate. The process and procedure is a metabolic multi-step pathway that happens in the cytoplasm of plant cells, animal cells, and the cells of various microorganisms.

The answer to the question above is:

1) nonspontaneous because deltaG is positive

2) glucose + ATP --> glucose-6-phosphate + ADP

3) -16.7 kJ/mol

4) yes, because deltaG is negative
