wariber [46]2 years ago
3 0

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.

Explanation:

have a nice day :)

Population Changes

Change is inevitable in nature.

Ecosystems have to cope with sudden changes like hurricanes and long term changes like ice ages.

Healthy Ecosystems will withstand the stress caused by change. Populations will recover or adapt to a new climate.

Population Changes

Stressed ecosystems do not handle change well.

They are already fragile or out of balance. They react with population spikes (boom) and population crashes (bust)

Population spike (boom)- Increase in population happens quickly.

Population crash (bust)- Decrease in population happens quickly

Sometimes a stressed ecosystem will not recover from change.

Population Effects Ecosystems

If a change affects one population in an ecosystem, the change will be felt throughout the system over time.

When one population of organisms increases or decreases, other populations will be affected because all living things are interrelated.

CH 4 History and Structure of the Atom
Butoxors [25]

Answer:

a) Cl, 17 protons and 17 electrons

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. The atomic number of chlorine is 17. Its means it has 17 protons and 17 electrons.

The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom. Thus the atomic mass of chlorine will be 17+18 = 35 amu

Number protons = 17

Number of electrons = 17

Number of neutrons = 18

Properties of Chlorine:

1. it is greenish-yellow irritating gas.

2. its melting point is 172.2 K

3. its boiling point is 238.6 K

4. it is disinfectant and can kill the bacteria.

5. it is also used in manufacturing of paper, paints and textile industries.

How many moles of sulfur<br> dioxide are in 2.26 x 10^33 sulfur dioxide molecules?
LUCKY_DIMON [66]

Answer:

moles = no. of molecules / Avogadro's number

         = 2.26 x 10^33 / 6.022 x 10^23

         = 3752906011

Round to significant figures which is 3 = 3.75 x 10^9 mol

Explanation: The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number

A 250 ml sample of saturated a g o h solution was titrated with h c l , and the endpoint was reached after 2. 60 ml of 0. 0136 m
nata0808 [166]

A 250 ml sample of saturated a g o h solution was titrated with h c l , and the endpoint was reached after 2. 60 ml of 0. 0136 m h c l was dispensed. Based on this titration, what is the k s p of a g o h <u>. Ksp=1.9×10⁻⁸</u>

<h3>What is titration?</h3>

Titration is a typical laboratory technique for quantitative chemical analysis used to calculate the concentration of a specified analyte. It is also referred to as titrimetry and volumetric analysis (a substance to be analyzed). A standard solution with a known concentration and volume is prepared as the reagent, also known as the titrant or titrator. To ascertain the concentration of the analyte, the titrant reacts with an analyte solution (also known as the titrand). The titration volume is the amount of titrant that interacted with the analyte.

A typical titration starts with a beaker or Erlenmeyer flask being placed below a calibrated burette or chemical pipetting syringe that contains the titrant and a little amount of the indicator (such as phenolphthalein).
