Answer: Two boxes of B would be required.

Explanation: From given information, A = 10 grams and B = 5 grams

C is made up of one A and one B box.

So, mass of C = mass of A + mass of B

mass of C = 10 g + 5 g = 15 g

number of boxes of C in 30 grams will be = 30g(\frac{1box}{15g})

= 2 boxes

So, if we want to make the two boxes of C then we also have to double the number of boxes of A and B.

Hence, to make 30 grams of C, we need to take two boxes of B since each box of C requires one box of A and one box of B.

Mass box C is 10+5. (So C is 15)

But if C was 30, how many times could you put B (5) into it?

30/5 = 6

You would need 6 boxes of B to make 30 grams of C.

What is the energy of a microwave photon that has a frequency of 9.86 x 1012 Hz?
BlackZzzverrR [31]

Answer:

6.533 × 10^-21J

Explanation:

The energy of the microwave photon can be calculated using:

E = hf

Where;

E = energy of photon (J)

h = Planck's constant (6.626 × 10^-34 J/s)

f = frequency (9.86 x 10^12 Hz)

Hence, E = hf

E = 6.626 × 10^-34 × 9.86 x 10^12

E = 65.33 × 10^(-34 + 12)

E = 65.33 × 10^(-22)

E = 6.533 × 10^-21J

The energy of the microwave photon is

6.533 × 10^-21J

All human body systems works together m. What would happen to someone if one of their systems becomes inefficient?
Reil [10]
They would most likely get sick. Or suffer from organ failure. When one part of your body doesn’t work it causes a weakness, making you more susceptible to sicknesses.

Which of the following is/are postulates of Dalton’s atomic theory? 1. Atoms combine in fixed ratios of whole numbers. 2. Atoms
motikmotik

Answer:

1 and 2

Explanation:

The postulates of Dalton's atomic theory are;

- Matter is made up of indivisible particles known as atoms.

- Atoms of same elements have same properties while atoms of different elements have different properties.

- Atoms of different elements combine in fixed ratios to form compounds.

- Atoms are neither created nor destroyed.

- The formation of new products (compounds) results from the rearrangement of existing atoms (reactants).

By comparing the postulates above and those in the questions, we find that only the following postulates are part of the daltons atomic theory;

1. Atoms combine in fixed ratios of whole numbers.

2. Atoms of each element have different properties.
