Answer:

salt and water

Explanation:

Mixture:

A mixture is made from two or more type of matter in any proportion. Mixture are generally two types:

1. Homogeneous mixture

This is also known as solution, in which the composition of the substances is uniform.

Lemon-flavored water is an example of homogeneous mixture because in this the composition of the substances is uniform.

2. Heterogeneous mixture

In this form of mixture the composition of substance are not uniform and the component of mixture also visible.

Stuffed mushrooms is an example of Heterogeneous mixture because in this form of mixture the composition of substance are not uniform and the component of mixture also visible.

a.flour and water : Heterogeneous mixture

b.sand and water Heterogeneous mixture

c.salt and water Homogeneous mixture Or solution because in which the composition of the substances is uniform.

d.oil and wate Heterogeneous mixture

e.ice and water Heterogeneous mixture

Answer:

The nucleus of the atom as suggested by "nuclear" chemistry.
Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
An excessive amount of protons or neutrons.
Periodic table, table O, and table N.
Personal opinion question.
The atomic number.
It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
Protons ---- element.
Random, self-generated.
Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
Neutrons and Gamma radiation.
Gamma radiation.
Electrons and Beta particles.
To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
The number of protons because they are what define the identity of an element.

Goodluck!

Why is oiling done time and again in a sewing machine???????

8_murik_8 [283]

If you are looking for a simpler maintenance timeline, oil your machine once after every fifty hours of use, or at the same time you can clean out the lint that may have built up in the machine various books and crannies.

Please help! (The question is in the picture above)

goldfiish [28.3K]

(i) The pH of HCl is between 0 and 2.
(ii) the presence of Carbon Dioxide turns lime water milky or sees a white precipitate form on the surface of the lime water. Lime water is CaOH and when it reacts with Carbon Dioxide it forms a white solid (precipitate) Calcium Carbonate.
$Ca(OH)_{2} _{(l)} + CO_{2} _{(g)} -----\ \textgreater \ CaCO_{3} _{(s)} + H_{2}O_{(l)}$

C₂H₄O₂ + O₂ ➞ CO₂ + H₂O

densk [106]

Answer:

C2H4O2 + 2O2 ==> 2CO2 + 2H2O

Explanation:

Start with the carbons

C2H4O2 + O2 ==> 2CO2 + H2O There are 2 on the left, so you need 2 on the right.

Next deal with the hydrogens. You have 4 on the left so you have to make 4 on the right

C2H4O2 + O2 ==> 2CO2 + 2H2O

The oxygens are the real devil in this question. Be careful how you handle them. There are 2 * 2 = 4 from the CO2 and 2*1 = 2 from the water. The total is 6

Now you can't just put a 3 in front of the O2. There are 2 in the given chemical. So you don't need 6. You need 6 -2 = 4. But the oxygen is O2. You have to divide the 4 by 2 to get 2

C2H4O2 + 2O2 ==> 2CO2 + 2H2O

And that's your answer.
