The cells split up into two to repair the damaged cell so it should be A.
Answer:
2.62*10^-3
Explanation:
To do this by hand, you need to understand the rules of scientific notation.
We can use the heat
equation,
<span>Q = mcΔT
</span>
Where Q is the amount
of energy transferred (J), m is the mass of the substance (kg), c is the
specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
In this problem there is no any data about initial temperature of the water. So, we can assume that given temperature of 5.2 °C as the temperature difference.
Q = 348 J
m = ?
c = 4.186 J g⁻¹ °C⁻¹
ΔT = 5.2 °C<span>
By applying the formula,
348 J = m x </span>4.186 J g⁻¹ °C⁻¹ x 5.2 °C<span>
m = 15.99 g
Hence, the grams of water is 15.99.</span>
