Answer:
400.197mmHg
Explanation:
P1V1 / T1 = P2V2 / T2
Where P1=524 mm Hg V1 =275 ml T1 = 35°C +273 = 308k
V2= 325-ml T2= 5°C+273 = 278k , P2= ?
Substituting the values into the formula.
524 mm Hg ×275 ml /308k = P2×325-ml/278k
Cross multiply
524 mm Hg ×275 ml×278k=308k×P2×325-ml
40059800= 100100×P2
P2 = 40059800/100100
P2= 400.197mmHg
Hence, the second pressure will be 400.197mmHg
Answer:
B. 4 ham slices
Explanation:
A chemical reaction involves one or more substances known as reactants combining chemically to give one or more substances known as products.
Reactants in chemical reactions combine in definite mole or mass ratios to give products. Therefore, when one substance is present in excess of what is required to combine with another to form products, that substance is known as the excess reagent. The other substance which is present in a smaller amount and which when used up, the reaction stops is known as the limiting reagent.
From the illustration of the sandwiches in the question, the recipe for one sandwich represents the chemical equation of a reaction. The equation form is given below:
2 cheese slices + 1 ham slice + 2 bread slices ---> 1 sandwich
The ratio of the reactant is 2 : 1 : 2
From the available ingredients, 12 cheese slices, 10 ham slices, 12 bread slices.
12 cheese slices will require 6 ham slices and 12 bread slices to produce 6 sandwiches.
However, since there are 10 ham slices, 4 ham slices will be left over unused. This is the excess or leftover reactant.
Answer:
0.159 moles of Ti
Explanation:
32.5 g of Ti x (1 mol of Ti / 204.4 g of Ti) = 0.159 moles of Ti
