ehidna [41]3 years ago
3 0

Answer:

2, 1, 2

Explanation:

Na + Br2 —> NaBr

To balance the equation, we do the following:

There are 2 atoms of Br on the right side and 1atom on the left side. It can be balance by putting 2 in front of NaBr as shown below:

Na + Br2 —> 2NaBr

Now, we have 2 atoms of Na on the right side and 1atom on the left. Thus, it can be balance by putting 2 in front of Na as shown below:

2Na + Br2 —> 2NaBr

Now, the equation is balanced.

The coefficients are 2, 1, 2

0.5 moles of any gas is at STP, it will occupy how many LITERS of volume?
never [62]

Answer: 500L

Explanation:

No of moles= volume× molarity/1000

No of moles =0.5moles

Volume=?

Molarity of a gas at stp = 1M

Stp means standard temperature and pressure

No of moles = volume ×molarity/1000

Substitute the values

0.5=volume×1/1000

Cross multiply

Volume = 1000×0.5

Volume = 500L

The volume is 500L

A student tested a sample of carbon (C) by combining it with water. There was no reaction between the carbon and water. The stud
svp [43]
I disagree. Carbon is not a group 18 element. This is incorrect because elements closer to the top of the group are less reactive than those at the bottom of the group. Group 18 elements are noble gases and carbon, a group 14 element, is a non metal.

A box of cleaning supplies weighs 15 N. If the box is lifted a distance of 0.60 m, how much work is done?
Nady [450]
Work Done = force x displacement. So in this case the 15N is the force (because weight is a force) and 0.60m is the displacement. Therefore 15 x 0.6 = 9 Joules of work done (btw, work done can also be referred to as energy transferred)
