<h3>
Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
Answer:
The answer is
<h2>324 K</h2>
Explanation:
To express a given temperature in degree Celsius to Kelvin simplify add 273 to the given value
That's
<h3>K = 273 + °C</h3>
where
K = Kelvin
°C = value in degree Celsius
From the question the value to be converted is 51°C
It's equivalent in Kelvin is
K = 273 + 51
We the final answer as
<h2>324 K</h2>

Answer:
compounds
Explanation:
Substances made of two or more elements that are chemically joined together are called <u>compounds</u>.
<em>Generally, elements are substances that contain just a type of atom. Compounds, on the other hand, contain different atoms (of different elements) that are chemically linked together. The linkage is referred to as bonding. The bonding could be covalent, ionic, or hydrogen bonding.</em>
