Answer:
204.8g
Explanation:
The number of moles of a substance is related to its mass and molecular mass as follows:
mole (n) = mass (m) ÷ molar mass (MM)
According to this question, 3.50 moles of sodium chloride (NaCl) is added to a food.
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Using mole = mass/molar mass
Mass = molar mass × mole
Mass = 58.5g/mol × 3.5mol
Mass = 204.75
Mass = 204.8grams.
Therefore, 204.8grams of NaCl or common salt was added to the food.
Answer:
Potassium dihydrogen phosphate is a potassium salt in which dihydrogen phosphate(1-) is the counterion. ... It is a source of phosphorus and potassium as well as a buffering agent. It can be used in fertilizer mixtures to reduce escape of ammonia by keeping pH low.
Explanation:
Sugar compound
Air Homogeneous mixture
Hot tea Homogeneous mixture
Salt water Homogeneous mixture
Element:
An element is a simplest type of a pure substance which is composed of only one type of matter. For examples; silver, gold platinum etc.
Pure substance:
A compound is a pure substance which is composed of two or more type of matter in definite proportion. For examples; water which is composed by Hydrogen and oxygen etc.
Mixture:
A mixture is made from two or more type of matter in any proportion. Mixture are generally two types:
1. Homogeneous mixture
This is also known as solution, in which the composition of the substances is uniform.
Lemon-flavored water is an example of homogeneous mixture because in this the composition of the substances is uniform.
2. Heterogeneous mixture
In this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Stuffed mushrooms is an example of Heterogeneous mixture because in this form of mixture the composition of substance are not uniform and the component of mixture also visible.
Answer:
Chemical Properties of Nonmetals
:
- Nonmetals are poor conductors of heat and electricity. ...
- Unlike metals, nonmetals aren't malleable and ductile.
- Nonmetals react more with metals than with nonmetals.
- Usually, nonmetals react with other nonmetals in high temperature.
- Most nonmetals do not react with air in room temperature.
