Inside stars in space, the nuclei of hydrogen atoms fuse together to form helium atoms. This represents which form of energy?
mixas84 [53]

Explanation:

When two small nuclei combine together to form a large nuclei then it is known as nuclear fusion.

When nuclei of two hydrogen atoms fuse together then it results in the formation of a helium atom along with the release of lot of energy. This energy is nuclear energy.

This nuclear reaction is as follows.

      ^{2}_{1}H + ^{3}_{1}H \rightarrow ^{4}_{2}He + ^{1}_{0}n + Energy

Thus, we can conclude that nuclear fusion represents nuclear energy.

Suppose we want to charge a flask with 1.6 g of sugar. We put the empty flask on a balance and it is determined to weigh 330 g.
RSB [31]

Answer:

total weight to expect = 331.60 grams

Explanation:

The flask wanted to be charged with 1.6 grams of sugar. The empty flask was weighed on a balance and it was determined to weigh 330 grams . The weight we would expect when we add the sugar can be computed as follows:

weight of the empty flask = 330 grams

weight of the sugar = 1.6 grams

The weight of the flask after adding the sugar will be the sum of the weight of the sugar and the empty falsk

Therefore,

Total weight to expect = 330 grams + 1.6 grams

total weight to expect = 331.60 grams

Identify the brønsted base in the forward reaction hpo2− 4 (aq) + hno3(aq) ⇀↽ no− 3 (aq) + h2po− 4 (aq). 1. h2po− 4 (aq) 2. hno3
Simora [160]
According to Bronsted theory of acid and base, an acid in a proton donor while base is a proton acceptor. Acid donates the proton to form conjugate base, while base accepts proton to form corresponding conjugate acid.

For the reaction,
<span>hpo2− 4 (aq) + hno3(aq) </span>⇔<span> no− 3 (aq) + h2po− 4 (aq)

In above forward reaction, hno3 donotes proton to form no-3, hence no-3 is a conjugate base. </span>
