Answer:
False
Explanation:
Water molecules are spread up but slightly, enough that none of the molecules actually move freely around each other. Only gas and plasma molecules are very spread apart.
Answer:
Calcium (Ca²⁺)
Explanation:
Calcium is very important mineral, found in teeth and bones primarily.
It is needed for the strong bones.
It is very important to maintain the bones in order to support our skeleton.
In our body it is also important to carry out other functions like in muscles, nerve function and also for heart.
If our diet is not full of calcium, the calcium deficiency may occur which leads to the weakening of bones and cause fracture.
The dietary source of calcium includes:
Yogurt, cheese, milk
beans such as peas, peanuts.
fishes
almonds, oranges, molasses
He put iron with sulfur and oxygen and it had a few more errors and iron is a metal the other two are nonmetals
Answer:
The value of an integer x in the hydrate is 10.
Explanation:

Molarity of the solution = 0.0366 M
Volume of the solution = 5.00 L
Moles of hydrated sodium carbonate = n


Mass of hydrated sodium carbonate = n= 52.2 g
Molar mass of hydrated sodium carbonate = 106 g/mol+x18 g/mol



Solving for x, we get:
x = 9.95 ≈ 10
The value of an integer x in the hydrate is 10.
