What is the mole ratio of D to A in the generic chemical reaction 3A + B C + 4D
ehidna [41]

Answer:- Mole ratio of D to A is 4:3.

Explanations:- Mole ratio for a chemical reaction is the ratio of the coefficients.

The given generic chemical reaction is:

3A+B\rightarrow C+4D

The numbers written in front of each chemical species in the chemical reaction are their moles. For the given generic chemical reaction the coefficient of A is 3 and that of B is 1. So, the mole ratio of A to B is 3:1.

Similarly if we want to write the mole ratio of C to D then it is 1:4.

We are asked to write the mole ratio of D to A. So, like the other ratios, the mole ratio of D to A is 4:3 as the coefficient of D is 4 and A is 3.

How many grams of Mg are needed to produce 224 g of MgO in the complete reaction of Mg
zmey [24]

Answer:

134.4 g of Mg

Explanation:

reaction:

2Mg + O2 ➡️ 2MgO

1) find the mol of MgO

mol = mass / molar mass

mass = 224 g

molar mass = 24+16 = 40

mol = 224 / 40

= 5.6 moles

2 mol = 5.6 moles

2) find the mass of Mg

mass = mol × molar mass

mol = 5.6

molar mass = 24

mass = 5.6 × 24

= 134.4 g

If an atom has 11 atomic number and 11 neutrons how many electrons are there??
Fantom [35]

Answer:

11 electrons

Explanation:

The atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
