Nuclear reactions in a reactor produce a lot of thermal
Leokris [45]

Answer:

Heat flows from the reactor to the water

Explanation:

The thermal energy mentioned in the description is another way to say heat. The energy that is produced by the nuclear reactions leaves the reactor and enters the water, warming it.

The passage does <em>not </em>say that heat flows in the form of electricity, but rather that the turbines turned by the steam produce electricity.

The passage does <em>not </em>say that the steam produces the heat, but rather that the boiling of the water (caused by the heat) produces steam.

Bromelain works by breaking the enzymes that cause browning into smaller molecules. Explain how the reaction that breaks up the
kenny6666 [7]

Bromelain separates the amino acids in the enzymes that cause browning by breaking the peptide bonds.

Explanation:

Enzymes speed up chemical reactions by lowering activation energy.

An enzyme from the stem of pineapple is called Bromelain also known as cysteine protease. It is obtained by cutting pineapple and filtering the juice of it.

Bromelain extract is a mixture of protein-digesting enzymes and several other substances in smaller quantities.

The monomers in Bromelain are numerous sub units of Sulfhydryl proteases. A free sulfyhydryl group of a cysteine amino acid side chain is required for function. By seperating proteins from amino acids the reaction  that breaks up enzymes occurs.

__H2 + __O2 --&gt; __H2O
nekit [7.7K]

Answer:

42.3moles

Explanation:

The chemical equation given in this question is as follows:

H2 + O2 → H2O

However, this equation is unbalanced, the balanced chemical equation is as follows:

2H2 + O2 → 2H2O

This equation shows that;

2 moles of hydrogen gas (H2) will produce 2 moles of water (H2O)

Hence, If 42.3 moles of water (H2O) are produced, 42.3 × 2/2

= 42.3moles of hydrogen was reacted.
