Im not sure but here is some information to help A declarative question is a yes-no question that has the form of a declarative sentence but is spoken with rising intonation at the end. Declarative sentences are commonly used in informal speech to express surprise or ask for verification.
Energy(heat) required to raise the temperature of water : 418.6 J
<h3>Further explanation </h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Specific heat of water = 4.186 J/g*C.
∆T(raise the temperature) : 10° C
mass = 10 g
Heat required :
Answer:
Sugar
Explanation:
Mixtures are substances that made of two or more elements or other substances that are joined together by physical methods and when mixed can be also be separated by physical method into the original individual elements.
Air is a mixture of gases such as oxygen, nitrogen, carbon dioxide and rare gases. When an amount of air is collected, its constituents can be collected separately.
Likewise 7 up and sea water
Sugar is a compound made of carbon, hydrogen and oxygen, when sugar is decomposed, it's original constituents are not recovered but sugar is decomposed into carbon dioxide and water
Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.
