g/L?
Chemistry

Answer 1) The density of the cube will be 17.30 g/mL

We know the edge that is 1 inch, we have to convert it into cc which will be;


1" = 16.38 cc and cc = mL


The given mass is in oz, we need to convert this as well in g;


10 oz = 283.495 g;


We have the formula as Mass = Density / Volume


Substituting the values; Density = (283.495 / 16.38) = 17.30 g/mL



So the density will be 17.30 g/mL


Answer 2) The density of cube will be 1.738 Kg/L


The same procedure of conversion would be done here,


Mass in Kg will be 0.02834 Kg and Volume will be 0.0163 L


On solving with the equation as Mass = Density /  Volume;


Density = (0.02834 / 0.0163) = 1.738 Kg/L


Hence, the density will be 1.738 Kg/L

Which way does equilibrium shift
Natali [406]
You can use Le Chatelier's Principle to describe the equilibrium shift.

Le Chaterlier's Principle states that: "<span>If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change."

Thus, if you heat up the reaction, the equilibrium shift favors the endothermic reaction. If you increase pressure (if gases are involved), the shift favors the reaction that produces less gaseous products (to counteract pressure) and so on.</span>

How many moles of water are produced from 40.0 g of C2H6?
inn [45]

Answer:

4 moles of water

Explanation:

this is a combustion reaction, so the balanced equation is: 2C2H6 + 7O2 → 4CO2 + 6H2O.

the molar mass of C2H6 is 30.07g, so 40.0 g of C2H6 is 1.33 moles of C2H6.

mole ratio of H2O to C2H6 is 6/2, or 3.

1.33 moles C2H6 * 3 moles H2O/1 mole C2H6 = 4 moles H2O

Plete the following problems significant figures: 6 × 0.30<br>​
jeka57 [31]
6= Only the digits 1 and 6 are the actual measured values. Therefore we have only 2 significant figures.

0.3= Zeros used as placeholders are not significant. Zeros that come before non-zero integers are never significant. Example 5: The zeros in 098, 0.3, and 0.000000000389 are not significant because they are all in front of non-zero integers. c. If the zeros come after non-zero integers and are followed by a decimal point, the zeros are significant.
