Answer:
2, 1, 1, 4.
Explanation:
Hello there!
In this case, for the given chemical reaction:
We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:
Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:
Which is now balanced so the coefficients 2, 1, 1, 4.
Best regards!
Answer : The final temperature of the metal block is,
Explanation :
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of aluminum = 55 g
= mass of water = 0.48 g
= final temperature = ?
= temperature of aluminum =
= temperature of water =
= specific heat of aluminum =
= specific heat of water=
Now put all the given values in equation (1), we get
Thus, the final temperature of the metal block is,
Answer:
Physical property
Explanation:
We can visualize the property without the need to do any experiments.
