If an atom has 17 protons, 15 neutrons, and 20 electrons, what is the atom's electrical charge?

3 0

The overall charge on this ion is -3. Neutrons don’t carry a charge, while protons and electrons carry a net +1 and -1 charge, respectively. In this case, the electrons outweigh the protons by 3, making the overall charge -3.

Hope this helps!

10.Which device is designed to produce
andreev551 [17]

Which device is designed to produce mechanical energy?

Well, mechanical energy is the sum of potential and kinetic energy. Kinetic energy is a unit of energy in which is the reason why an object does movement, while potential energy is another unit of energy in which is the reason why an object doesn't move, or stops. While you can stop a fan or a lamp, it isn't automatic. It's manually. So the answer is (4) an oven because mechanical energy happens automatically, not manually, or for a greater reason.

Carbon-14 has a half-life of 5720 years and this is a first order reaction. If a piece of wood has converted 75% of the carbon-1
liraira [26]

Answer: 1145.8 years

Explanation:

Half-life of carbon-14 = 5720 years

First we have to calculate the rate constant, we use the formula :

k=\frac{0.693}{5720\text{years}}

k=1.21\times 10^{-4}\text{years}^{-1}

Now we have to calculate the age of the sample:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  = 1.21\times 10^{-4}\text{years}^{-1}

t = age of sample  = ?

a = let initial amount of the reactant  = 100 g

x = amount decayed = 75 g

a - x = amount left after decay process  = 100 - 75 = 25g

Now put all the given values in above equation, we get

t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}

t=1145.8years
