Chemistry

shtirl [24]3 years ago

It can be shown that matter is neither created nor destroyed in a chemical reaction by taking a critical look at the each atom in both sides of the reaction (reactant and product sides).

1 atom of Mg started the reaction and 1 atom is also present in the products.

8 atoms of O are present in the reactants and 8 is also present in the products.

4 H atoms are present in the reactants and 4 are also present in the products.

2 N atoms are present in the reactants and 2 are also in the products.

In other words, the total number of each atom that is present in the reactants are also present in the product. Nothing has been lost during the reaction, although, the forms of each atom might have changed.

What is diabetes? How does it disrupt normal cellular activities? What are the overall consequences for your body?
Vlad1618 [11]

Answer:

Diabetes is a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it's an important source of energy for the cells. Cells are everywhere including the blood, bones and muscles. When you have diabetes, you don’t have enough insulin in your blood (an organ in your body called the pancreas makes insulin). Insulin controls the movement of blood sugar into the cells of the body.

Which representation of a hydrogen molecule is not correct?
USPshnik [31]

Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.

<h3>What is a double bond?</h3>

A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.

A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.

Therefore, hydrogen molecules cannot form a double bond.
