The answer is D. The rice cooker / pot.
hope this helps !
Answer:
I'd say it's a mixture, because you are putting different ingredients together to make something new; aka this salad.
Answer:
14.533 grams of solid precipitate of mercury(II) dichromate will form.
Explanation:

Moles of mercury(II) acetate = 
Moles of sodium dichromate = 
According to reaction , 1 mole of sodium dichromate reacts with 1 mole of mercury(II) acetate , then 0.045906 moles of sodium dichromate will recat with :
of mercury(II) acetate
This means that mercury(II) acetate is present in an excess amount and sodium dichromate is present in limiting amount.So, amount of precipitate will depend upon moles of sodium dichromate.
According to reaction , 1 mole of sodium dichromate gives 1 mole of mercury(II) dichromate , then 0.045906 moles of sodium dichromate will give :
of mercury(II) dichromate
Mass of 0.045906 moles of mercury(II) dichromate:
0.045906 mol × 316.59 g/mol = 14.533 g
14.533 grams of solid precipitate of mercury(II) dichromate will form.
706000 in scientific notation is 7.06x10^5
The given unbalanced equation is as follow,
Sn + H₃PO₄ → H₂ + Sn₃(PO₄)₄
In above equation first let get start with Sn, on left side its one and on right side its 3. So, multiply Sn on left side with 3 to balance Sn, Hence,
3 Sn + H₃PO₄ → H₂ + Sn₃(PO₄)₄
Now, balance Phosphorous, on left side it counts one and on right side it counts 4, so multiply H₃PO₄ on left side with 4 to balance P, Hence,
3 Sn + 4 H₃PO₄ → H₂ + Sn₃(PO₄)₄
Oxygen on both left and right are 16 in number, Hence it is balanced,
Hydrogen on left hand side are 12 in number, while that on right hand side only 2, So, multiply H₂ on right side by 6 to balance hydrogen atoms.
<u>3</u> Sn + <u>4</u> H₃PO₄ → <u>6</u><u> </u>H₂ + Sn₃(PO₄)₄
Above equation is balanced, and coefficients are highlighted bold and underlined.
