heat required: 169452 Joules

  • use the formula, Q = mcΔT

<u />

<u>Q is heat required, m is mass in kg, c is s.h.c , ΔT is change in temperature</u>

  • Here, the units of s.p.c and mass matches, in grams
  • if did not match, we have to convert into specific unit.

↪ Q = 1500 * 4.184 * (52-25)

↪ Q = 169452 J

  • Mass=1500g=m
  • ∆T=52-25=27°C
  • Specific heat capacity=c=4.184J/g°C

Apply thermodynamics

\\ \rm\rightarrowtail Q=mc\delta T

  • Q is heat

\\ \rm\rightarrowtail Q=1500(4.184)(27)

\\ \rm\rightarrowtail Q=169452J

Temperature depends on the average kinetic energy of athe particles in a sample how does this help with explaining why a plasma
Kryger [21]
Most particles in the plasma are heavy and slow and this statement explains why a plasma based light does not have a high temperature. The correct option among all the options that are given in the question is the third option. It is a fact that a heavy nuclei always takes more time to reach a thermal equilibrium.

Mg + 2H20 + Mg(OH)2 + H2 + 353kJ
mixer [17]

Answer:

m_{H_2O}=8.9g

Explanation:

Hello,

Based on the given reaction, since magnesium and water are in a 1:2 molar ratio at the reactants, we must apply the following stoichiometric factors to compute the complete reaction of the 6.0 g of magnesium:

m_{H_2O}=6.0gMg*\frac{1molMg}{24.305 gMg}*\frac{2molH_2O}{1molMg} *\frac{18gH_2O}{1molH_2O} \\\\m_{H_2O}=8.9g

Best regards.

Determine the concentration of a solution prepared by diluting 25.0 ml of a stock 0.188 m sr(no3)2 solution to 150.0 ml
o-na [289]
We can use the following equation to calculate the concentration of diluted solution.
c1v1 = c2v2 
where c1 is concentration and v1 is volume of stock solution, which is the more concentrated solution.
c2 is concentration and v2 is the volume of diluted solution.
substituting the values in the equation,
0.188 M x 25.0 mL = c2 x 150.0 mL 
c2 = 0.0313 M
concentration of diluted solution is 0.0313 M
