Answer:
46.67 g
Explanation:
From the question given above, the following data were obtained:
Change in temperature (ΔT) = 23.8 °C
Heat (Q) = 261 J
Specific heat capacity (C) of silver = 0.235 J/gºC
Mass of silver (M) =?
The mass of the sample of silver can be obtained as follow:
Q = MCΔT
261 = M × 0.235 × 23.8
261 = M × 5.593
Divide both side by 5.593
M = 261 / 5.593
M = 46.67 g
Thus, the mass of the sample of silver is 46.67 g
Answer: 3.5 moles V2O5
Explanation: First balance the chemical equation to find the stoichiometric factor between VOCl3 and V2O5
2 V2O5 + 6 Cl2 => 4 VOCl3 + 7 O2
So the mole to mole ratio is 2 moles V2O5 to 4 moles of VOCl3
Solution
7 moles VOCl3 x 2 moles V2O5 / 4 moles VOCl3 = 3.5 moles V2O5
Answer: A tick on a deer

The downside of this is that the longer lasting material is more difficult to break down.
Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.
The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

Assuming It is Iron (II)
Na2CO3 + Fe(CLO2) --> FeCO3 + Na2(CLO2)
FeCO3 forms a precipitate in aqueous solution
(2Na+) + (Fe2+) + (CLO2(2-)) + (CO3(2-)) --> FeCO3 + (2Na+) + (CLO2)(2-))
Sodium and Chlorite ions become spectator ions as they do not form precipitates on both sides of equations
(Fe2+) + (CO3(2-)) --> FeCO3
