Answer:
1.rate of reaction should be indicated by symbols 2.we should indicate physical states by sybloms 3.reversible reaction should be indicated by using double arrows
Answer:
B.) 129.9 grams
Explanation:
To find the mass, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> ΔT = change in temperature (°C)
The specific heat of copper is 0.385 J/g°C. Knowing this, you can plug the given values into the equation and simplify to isolate "m".
Q = mcΔT <----- Equation
5000 J = m(0.385 J/g°C)(200 °C - 100 °C) <----- Insert values
5000 J = m(0.385 J/g°C)(100) <----- Subtract
5000 J = m(38.5) <----- Multiply 0.385 and 100
129.9 = m <----- Divide both sides by 38.5
Ni = Nickel
SO4 = Sulphate
2 and 3 in the sub-script are the charges.
So , its name is NICKEL SULPHATE
since, a,b is an acid.. imposibble it is the answer
we left with c and d
while we can see that 'hyroxide' is a base
answer: C
The correct answer is B. The equation that represents the process of photosynthesis is: 6CO2+12H2O+light->C6H12O6+6O2+6H2O. <span>Photosynthesis
is the process in plants to make their food. This involves the use carbon
dioxide to react with water and make sugar or glucose as the main product and
oxygen as a by-product.</span>
