The mass, in grams, of the chlorine gas will be 0.84 grams
<h3>Mass of gases at STP</h3>
At standard temperature and pressure, 22.4 L of gas has 1 mole of the gas in it.
This time, what we have is 265 mL of the gas at STP. 265 ml is equivalent to: 265/1000 = 0.265 L
If.
22.4 L = 1 mole
Then,
0.265 L = 0.265 x 1/22.4 = 0.01183 moles
This means that 0.01183 moles of chlorine is present in the gas at STP.
Mass of 0.01183 moles of chlorine = moles x molar mass.
The molar mass of chlorine gas is 71
Mass of the chlorine gas = 0.01183 x 71 = 0.84 grams

Sunspots Are decreased temperature areas. So it might be bright all around the sun spots, and the dark spots are where the temperature is lower. They usually form in polar pairs, meaning that on the other side in the same spot there would be another sunspot
1) False, an unbalanced force is needed or the object will stay in place.
2) True, weight is the amount of force gravity is putting on an object.
4) True, net force is equal to the mass of the object multiplied by the acceleration of an object.
5) False, however I'm not completely sure on this one.
6) Force is any interaction that will change the motion of an object.
7) vertical
8) horizontal
9) horizontal.
10) vertical or both.
It’s oxygen
The formula is carbon dioxide + water + sunlight = oxygen + glucose
Therefore, you don’t need oxygen as it’s a product
<span>Why are valence electrons important?
Valence electrons are the electrons present farthest from nucleus. These valence electrons are either transferred or shared during a reaction. Some elements like metals donate valence electrons in ionic compound formation, while some like Carbon mutually share thier valence electrons to make a covalent bond. Hence, it is the valence electrons that make any element reactive or unreactive.
</span><span>Why do elements bond?
Elements react in order to gain stability. This stability is gained in the form of attaining noble gas configuration either by donating, gaining or mutually sharing their valence electrons.
</span><span>What are two ways elements complete their valence?
The two ways are transfer of electrons and mutual sharing of electrons.
Example:
Sodium looses one valence electron to obtain Noble gas configuration of Neon which is more stable configuration.
Chlorine gains one electrons to obtain Noble Gas configuration of Argon which is more stable configuration.
Carbon mutually shares its four valence electrons with four atoms of Hydrogen having one electron per atom to complete its octet.</span>
