Answer:
<u>reaction are equal.</u>
Explanation:
The law of the conservation of mass states that the total mass before and after a reaction are equal.
In a reaction, the mass of the reactants are always equal to the mass of the products. Nothing ever disappears from the equation, although substances may become gas and "disappear" the air.
Answer:
it can allow more room for additional living things in the habitat
Explanation:
Use water for an example.
- Taking water can destroy a fish habitat.
- Using excess water can cause water to run out.
- Taking/using water leaves less amounts for others/organisms.
Taking water does not allow additional room for organisms in a habitat.
Answer:
This snip might help...it depends :)
Explanation:
The mass of lime that can be produced from 4.510 Kg of limestone is calculated as below
calculate the moles of CaCO3 used
that is moles =mass/molar mass
convert Kg to g = 4.510 x1000 =4510g
= 4510 / 100 =45.10 moles
CaCO3 = CaO +O2
by use of mole ratio between CaCO3 to CaO (1:1) the moles of CaO is also= 45.10 moles
mass of CaO = moles x molar mass
45.10 x56 = 2525.6 g of CaO
