Answer: yes even temperature too in rarely case
Explanation:
Given that,
Volume of a hallow glass sphere is 350 mL
Specific gravity is 1.252
We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.
The density of water is 1 g/mL
We know that,
1 pound = 453.592 grams
So,
m = 0.97 lbs
So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
Atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons
protons and neutrons are located inside the nucleus and electrons are found in energy shells around the nucleus. Protons are positively charged, electrons are negatively charged and neutrons are neutral. elements in their ground state are neutral with equal amounts of protons and electrons.
Atomic number is the number of protons. atomic number is characteristic for the element.
atomic number of Be is 4 therefore Be has 4 protons
answer is B. 4
When elements are combined to form compounds, they undergo chemical change in which the properties of the composing elements are always different from the compounds formed after reaction. The change is not only applicable to the chemical properties of the elements but also the physical states of the substances. Answer then is B.
