Answer:-
0.229 L
Explanation:-
Molar mass of AgBr = 107.87 x 1 + 79.9 x 1
=187.77 grams mol-1
Mass of AgBr = 150 grams
Number of moles of AgBr = 150 grams / 187.77 gram mol-1
= 0.8 mol
The balanced chemical equation is
NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)
From the equation we can see that
1 mol of AgBr is produced from 1 mol of AgNO3.
∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.
Strength of AgNO3 = 3.5 M
Volume of AgNO3 required = Number of moles / strength
= 0.8 moles / 3.5
=0.229 L
The top one is different from the bottom because of is curvature shape while the bottom one is a square shape i think the bottom will heat up faster because of the nice even area inside where heat waves can evenly flow
CUSO4 is an example of A COMPOUND.
A compound is the product formed when two or more elements chemically combine together to form a new product or products, which are quite different from the reactants. The elements in the compound are usually combined together in a specific ratio. In the question given above, CUSO4 is a compound because, copper, sulphur and oxgyen had combined together chemically to form a new compound, which is CUSO4. The ratio of combination is 1:1:4, that is, one atom of copper combine with one atom of sulphur and four atoms of oxygen to form one molecule of CUSO4.
I think the correct answer among the choices presented above is option A. An ore is rock that contains a mineral or metal with economic usefulness. Examples are copper ore, gold ore and iron ore. These ores are being extracted from the Earth by mining.
