Answer:

N for chlorate ion is one

Explanation:

Because N is the number of electrons needed to form octet structure causing a negative charge of one, since it already has 25valence electrons

there are several ways of producing electrical energy (coal,hydrpower,nuclear power,solar,wind,geothermal,etc.)but which way is

dlinn [17]

Well, that depends on cost, maintenance, and power output most of the time. Geothermal seems to be best because you could heat up water, and the heat from said water can be used to create electricity. Making it extremely eco-friendly, which makes it the best in that regard.

How much heat, in joules and in calories, must be added to a 75.0Â–g iron block with a specific heat of 0.449 j/g Â°c to increas

lianna [129]

Answer:

$Q=50,849.25J\\\\Q=12,153.3cal$

Explanation:

Hello!

In this case, given the mass, temperature change and specific heat, it is possible to compute the required heat in joules as shown below:

$Q=mC(T_2-T_1)\\\\Q=75.0g*0.449\frac{J}{g\°C}(1535\°C-25\°C)\\\\Q=50,849.25J$

Now, since 1 cal =4.184 J, this result in calories is:

$Q=50,849.25J*\frac{1cal}{4.184J}\\\\Q=12,153.3cal$

Best regards!
