7 0

Answer:

Boiling point of gold is 1630 ^{0}\textrm{F} or 3239.15 K

Explanation:

We know, T(^{0}\textrm{F})=1.8T(^{0}\textrm{C})+32

Here T(^{0}\textrm{C}) and T(^{0}\textrm{F}) are temperature in degree centigrate and temperature in degree farhenite respectively.

So, 2966^{0}\textrm{C}=\frac{2966-32}{1.8}^{0}\textrm{F}

                                            = 1630 ^{0}\textrm{F}

We know, 1^{0}\textrm{C}=273.15 K

So, 2966 ^{0}\textrm{C} = (2966+273.15) K = 3239.15 K

If an object has a Mass of 11g and a volume fo 13mil, what is its density?
Nimfa-mama [501]

Answer:

\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}

Explanation:

Density is found by dividing the mass by the volume.

d=\frac{m}{v}

The mass of the object is 11 grams and the volume is 13 milliliters.

m= 11 \ g \\v= 13 \ mL

Substitute the values into the formula.

d= \frac{11 \ g}{13 \ mL}

Divide.

d=0.846153846 \ g/mL

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.

d \approx 0.85 \ g/mL

The density is about <u>0.85 grams per milliliter.</u>

Aluminum metal reacts with aqueous cobalt(II) nitrate to form aqueous aluminum nitrate and cobalt metal. What is the stoichiomet
Lelu [443]

Answer:

the stoichiometric coefficient for cobalt is 3

Explanation:

the unbalanced reaction would be

Co(NO₃)₂+ Al → Al(NO₃)₃ + Co

One way to solve is to build a system of linear equations for each element (or group as NO₃) , knowing that the number of atoms of each element is conserved.

For smaller reactions a quick way to solve it can be:

- First the Co as product and as reactant needs to have the same stoichiometric coefficient

- Then the Al as product and as reactant needs to have the same stoichiometric coefficient

- After that we look at the nitrates . There are 2 as reactants and 3 as products . Since the common multiple is 6 then multiply the reactant by 3 and the product by 2.

Finally the balanced equation will be

3 Co(NO₃)₂+ 2 Al → 2 Al(NO₃)₃ + 3 Co

then the stoichiometric coefficient for cobalt is 3
