Answer

1. 1cm=10mm, 1kg=1000g and 12in=1 ft

2. 50mm=5cm

    48 in =4ft

     36ft=12 yd

     2.5m=250cm

     1000mL= 1 L

Explanation

if 1cm=10mm then 5cm=?

5×10=50mm

if 12 in =1ft then 48in=?

48/12 =4 ft

if 1m=100cm, then 2.5m=?

2.5×100= 250cm

and when know from capacity that 1000mL is equivalent to 1 liter.

Answer:

1. 50mm, 2. 4ft, 3. 4ft, 4. 250cm, 5. 1L

Explanation:

1. 1cm = 10mm

5cm = y mm = y = (5*10)/1 = 50mm

2. 12in = 1ft

48in = yft

y ft = (48*1) / 12 = 4ft

3. 1ft = 3yd

Z ft = 12yd

Z ft = (12*1)/3 = 4ft

4. 1m = 100cm

2.5m = x cm

X = (100*2.5) / 1 = 250cm

5. 1mL = 1*10⁻³L

1000mL = z L

z L = (1000 * 1*10⁻³) / 1

Z L = 1L

1000mL = 1L.

Og is the noble gas after Rn. To go from [Rn] to [Og], you must fill four subshells (s, p, d, and f) with a total of 32 electron
Marianna [84]

Answer:

See explanation

Explanation:

Since we have to fill five subshells in moving from Og to the next noble gas in the eight period, we have to know the maximum electrons contained in each of those subshells;

s= 2, p=6, d= 10, f= 14, g = 18

This means that we need a total of 50 electrons to fill all the five subshells.

Hence, the element just below Sg in the eight period will have an atomic number of 156.

Nady [450]

Answer:

200 mol

Explanation:

2C8H18+25O2=16CO2+18H2O

2 mol → 16 mol

25 mol → X mol

X=25×16÷2=200

Which of the following statements about enthalpy is true?
Evgesh-ka [11]

Answer:    A chemical process must occur and then changes between the state of the reactants and the state of the products can be determined

Explanation:  Enthalpy represents the sum of the energy of the system with the product of the pressure and volume of that system. As a thermodynamic property, it expresses the ability to release heat from the system. In fact, enthalpy  tells us how much heat and work has changed during the chemical reaction under constant pressure. When measuring, measurements of the difference in enthalpy between the two states of the system is performed, before and after the chemical reaction, since total enthalpy can not be measured. This measurement of the enthalpy change can tell us, for example, whether the heat was released from the system during the reaction, or the system absorbed the heat.

A block of iron has a mass of 150 g and a volume of 20 ml. What is the density of iron? *
shtirl [24]

Answer:

<h3>The answer is 7.50 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of iron = 150 g

volume = 20 mL

We have

density =  \frac{150}{20}  =  \frac{15}{2}  \\

We have the final answer as

<h3>7.50 g/mL</h3>
