For a human to survive we require amounts of glucose which is readily found in sugar. example-when people say their sugar levels are low they tend to be more exhausted and less energetic. this is actually a lack of glucose in the body and can be replaced by ingesting a amount of it. however glucose isn’t only found in sugar but can be found in a variety of foods. so sugar doesn’t give us energy - it’s the glucose within it.

If i combined 15.0 grams of calcium hydroxide with 75.0 ml of 0.500 m hcl, how many grams of calcium chloride would be formed?
Zina [86]
The equation is:
Ca(OH)₂(s) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂<span>O(l)
</span>

n=mass in g/M.M

15 g Ca(OH)₂ is n=15 g/ 74.1 g/mol=0.2024 mol of Ca(OH)₂

no. of mol of HCl:

n=0.5 mol/L*0.075L=0.0375 mol

This could react with 0.0375/2= 0.01875 mol of Ca(OH)₂ We have a lot more than that.

Therefore, HCl is the limiting reagent and determines how much CaCl₂ forms.

Based on the balanced reaction, 2 moles of HCl gives 1 mole of CaCl₂

no. of mol of CaCl₂= 0.0375/2= 0.01875 mol

mass in g=n*MM= 0.01875*111= 2.08 g

A cube with sides 3cm.Its mass is 54g. will it sink or float
zloy xaker [14]

Answer:

It will sink.

Explanation:

Density of water=1gm/cc (In CGS)

Volume of cube=l^3 =3^3= 27cc

Mass of cube =54gm

Density of cube=M/V =54/27 =2gm/cc

Here, density of cube is greater than that of water. So, the cube sinks.
