Answer:
8.08 grams
Explanation:
Given;
Mass of the steam, m = 100 g
Change in temperature of water = (95°C - 35°C) = 60°C
Change in temperature of steam = (110°C - 100°C) = 10°C
let the mass of water by 'M'
also,
We know
specific heat of water, c = 4.184 J/Kg.°C
And, specific heat of steam, C = 2.03 J/Kg.°C
Now,
Heat released = Mass × specific heat × change in temperature
thus, for the condition given in the question
M × 4.184 × 60 = 100 × 2.03 × 10
or
M = 8.08 grams
The mass of water that will provide the same amount of heat when cooled from 95.0 to 35.0 C as a 100 g of steam cooling from 110C to 100C is 125 grams. To solve this question, we used the specific heat of water, calculated the heat produced in the latter scenario, and deduced the mass needed from that.
To determine the mass of water that will provide the same amount of heat when cooled from 95.0 to 35.0 C as a 100 g of steam cooling from 110 to 100C, we need to first calculate the amount of heat produced in the latter situation. Using the specific heat of water which is 4.184 J/g °C, the heat produced when cooling 100g of steam from 110C to 100C is Q=msΔT, where m is mass, s is specific heat, and ΔT is temperature difference. So, Q = 100g * 4.184 J/g°C * (110°C - 100°C) = 4184 J.
Now, we have to calculate the mass of water that will produce the same amount of heat when cooled from 95°C to 35°C. We rearrange the equation to solve for mass. Hence, m = Q/sΔT = 4184 J / 4.184 J/g°C / (95.0 °C - 35.0 °C) = 125g. Therefore, 125g of water will provide the same amount of heat when cooled from 95.0 to 35.0 C.

The chemical equation 2 C₂H₂ +5 O₂ + 4 CO₂ + 2 H₂O is the equation which represents the combustion of a hydrocarbon.
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
