The answer to this question is change in temperature will be 6.1 and specific specific heat capacity of metal will be 1698.36.

According to the formula of Calorimetry

Q = msΔT

where, Q = Quantity of heat absorbed (in joules)

M = Mass of water sample given (in kilogram)

S = specific heat capacity of metal

ΔT = Change in temperature

We have given,

Mass as 25 gram which is equal to 0.025 Kg.

Change in temperature as 6.1

Quantity of heat absorbed as 259 J

Applying to the formula of Calorimetry

Q = msΔT

259 = 0.025 × s × 6.1

s = 1698.36

So, specific heat capacity of metal came out to be 1698.36 and the change in temperature will be 6.1

How many grams of HNO3 it is required to play 8.75gr N2O<br> 4ZN + 10HNO3-4ZN ( NO3 ) 2 + N20 + 5H2O

Y_Kistochka [10]

Molar mass

HNO₃ = 63.02 g/mol

N₂O = 44.013 g/mol

The balanced equation is :

<span>4 Zn + 10 HNO₃ = 4 Zn(NO₃)₂ + N₂O + 5 H₂O
</span>
10 * 63.02 g HNO₃-----------> 44.013 g N₂O
? HNO₃ -----------------> 8.75 g N₂O

Mass HNO₃ = 8.75 * 10 * 63.02 / 44.013

Mass HNO₃ = 125 g

hope this helps!

The center on your school’s basketball team is 6 ft 10 in tall. How tall is the player in millimeters (mm)?

svp [43]

The answer is 6 ft 10 inches in millimeters (mm) is 0.833 ft.

Given,

The center of the school's basketball team is 6 ft 10 inches tall.

We have to convert the height of the player from feet and inches to feet.

Using the conversion factor,

1 ft = 12 inches

or, 12inches/ 1 ft

Converting 6ft 10 inches to ft, we get;

10 inches × 1 ft/ 12inches

= 0.833 ft

Therefore 6 ft 10 inches in millimeters (mm) is 0.833 ft.

Unit conversion is a method in which we multiply or divide with a particular numerical factor and then finally round off to the nearest significant digits.
