Answer:

D. 108g of water

Explanation:

16g CH4 produces 2(18)g of H20

1g CH4 produces $\frac{36}{16}$ g of H2O

48g CH4 produces $\frac{36}{16}$ ×48

108g of H20

zlopas [31]

Answer:

Volume = 75 inch³

Explanation:

Given data:

Area = 12.5 inch

Height = 6 inch

Volume =?

Solution:

Volume = height × length × width

Volume = Area × height

Now we will put the values in formula;

Volume = 12.5 inch² × 6 inch

Volume = 75 inch³

slader An experiment is carried out where 13.9 g of solid NaOH is dissolved in 250.0 g of water in a coffee-cup calorimeter. Dis

kvv77 [185]

Answer:

The mass of the surrounding is $M_t = 263.9 \ g$

Explanation:

From the question we are told that

The mass of $NaOH$ is $m = 13.9 \ g$

The mass of water is $m_w = 250.0g$

The chemical equation for the dissociation process is

$NaOH _{(s) } ---> Na^{+}_{(aq)} + OH^{-} _{(aq)}$

The specific heat capacity of the mixture is $c_p = 4.18 J g^{-1} C^{-1}$

The combined mass of the solution is

$M_t = 13 + 250$

$M_t = 263.9 \ g$

The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is

$M_t = 263.9 \ g$
