Please answer this question!
Hunter-Best [27]

1,2-dimbromopropane would be something like C which is the second best answer.

B would be correct if it had another carbon.

A is like C but incorrect for the same reason. 1,2-dibromoethane is what A is.

The answer has to be D where the bromines are right across from each other.

What observation did Rutherford make from his gold-foil experiment which
JulsSmile [24]

Answer:

A piece of gold foil was hit with alpha particles, which have a positive charge. Most alpha particles went right through. This showed that the gold atoms were mostly empty space. Some particles had their paths bent at large angles. A few even bounced backward. The only way this would happen was if the atom had a small, heavy region of positive charge inside it.

Which component of a plant makes the cell walls around plant cells tough and allows branches, stems, and leaves to be strong
Vsevolod [243]
<h3><u>Answer;</u></h3>

Cellulose

<h3><u>Explanation</u>;</h3>
  • Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
  • <em><u>It  is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
  • <em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very  strong.</u></em>
  • The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.

Which of the following polyatomic ions will form an ionic compound with two sodium ions? CO32− HCO31− NO21− NO31−
BaLLatris [955]

Answer:

CO32−

Explanation:

We have to consider the valencies of the polyatomic ions involved. Recall that it is only a polyatomic ion with a valency of -2 that can form a compound which requires two sodium ions.

When we look closely at the options, we will realize that among all the options, only CO32− has a valency of -2, hence it must be the required answer. In order to be double sure, we put down the ionic reaction equation as follows;

2Na^+(aq) + CO3^2-(aq) ---------> Na2CO3(aq)
