Answer:

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

When looking at Newman projections are there instances where the staggered confirmation is not the lowest in energy? Explain you

stiks02 [169]

Answer:

let's summarize the caution as we are given with human projection. We have to tell them stances where staggered confirmation is not the lowest in energy. Okay, so let's see that. Are there any instances that which conforms tiger is not the lowest energy. Okay, so the lowest energy is what then happened? The lowest in energy already happens on living. Honestly, when, when it happens the lowest in energy only happens when the bulky groups are at 1 80 degree with each other. When it happens when bulky, bulky, bulky groups are at 1 80 degree. Okay, When they are, for example, when the bulky groups are in this way At 180°, then it is Louis Why? Because repulsion are very less repulsion very less. Got it. So we have to tell when it is not the lowest so far not the lowest instance. These bulky groups should be together. So if they either make of angle of 60° or 300° together, suppose this is a bulky group one and this is a bulky group two and okay, so if it makes a 60 degree or 300 degree then this um have the highest energy Or has the energy is not lowest in it. Why? It is not lowest in it Because at 300° or 60°. Why? Because the pulsations are very high repulsion. Are you ready? Hi. So by looking at the humans projection we can conclude that when the if the bulky group parrot 1, 80 degree be considered as the lowest energy. And if they are at 300 or 60 degree or close to each other, republicans are higher and they are not in lowest energy.

calculate the number of oxygen atoms in a 90.0g sample of vanadium(v) oxide v2o5. be sure your answer has a unit symbol if neces

Alborosie

90.0 g of vanadium (V) oxygen sample has 1.50 x 10 24 oxygen atoms.

To determine the number of oxygen atoms in a vanadium oxide sample, the following steps must be made.

Step 1: Convert the mass of vanadium(V) oxide to mol of vanadium(V) oxide

mol vanadium(V) oxide = mass / molar mass

mol vanadium (V) oxide = 90.0 g / 181.88 g/mol

mol vanadium (V) oxide = 0.49483 mol

Step 2: Convert mol of vanadium (V) oxide to moles of oxygen using mole ratio

mol oxygen = mol vanadium (V) oxide * mole ratio O / mol V2O5

mol oxygen = 0.49483 mol * 5 mol O / mol V2O5

mol oxygen = 2.47416 mol O

Step 3: Convert to oxygen atoms using Avogadro's number

atoms oxygen = mol oxygen * 6.02214 x 10 23 atoms O /mol O

atoms oxygen = 2.47416 mol O * 6.02214 x 10 23 atoms O/mol O

atoms oxygen = 1.48997 x 10 24 atoms or 1.50 x 10 24 atoms O

A 27.3 g marble sliding to the right at 21.0 cm/s overtakes and collides with a 11.7 g marble moving in the same direction at 12

NISA [10]

Answer:

The answer to this is

The velocity of the 27.3Kg marble after collision is = 16.24 cm/s

Explanation:

To solve the question, let us list out the given variables and their values

Mass of first marble m1 = 27.3g

Velocity of the first marble v1 = 21.0 cm/s

Mass of second marble m2 = 11.7g

Velocity of the second marble v2 = 12.6 cm/s

After collision va1 = unknown and va2 = 23.7 cm/s

From Newton's second law of motion, force = rate of change of momentum produced

Hence m1v1 + m2v2 = m1va1 + m2va2 or

va1 = (m1v1 + m2v2 - m2va2)÷m2 or (720. 72-277.29)÷m1 → va1 = 16.24 cm/s

The velocity of the 27.3Kg marble after collision is = 16.24 cm/s

6) A rectangular fish tank is 70.00 cm long, 300.00 mm wide, and 300.00 m deep.

KATRIN_1 [288]

Answer:

Volume of water it can hold 63000,000 cm³

Mass of water is 63000,000 g.

Explanation:

Given data:

Length of tank = 70.00 cm

Width of tank = 300.00 mm

Height of tank = 300.00 m

Volume of water it can hold = ?

Mass of water = ?

Solution:

First of all we will convert the units into same unit.

Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm

Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm

Volume of water it can hold:

V = l×w×h

V = 70.00 cm × 30 cm × 30000 cm

V = 63000,000 cm³

Mass of water:

Density of water from literature = 1 g/cm³

d = m/v

1 g/cm³ = m/ 63000,000 cm³

m = 63000,000 g
