Answer:
Yes
Explanation:
Electrolysis is an example of redox reaction because reduction takes place at cathode and oxidation takes place at anode and both of these reactions take place simultaneously.
Which elements belong to the same group?
N, P, As,Sb
Ne, F, Ar,Kr
Rb, Sr, Y, Zr
K, Ca, Mg, Be
Match the following family of elements to its group.
Explanation:
To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.
The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.
The vertical arrangement of elements on the periodic table is the group. The horizontal arrangement of elements is the period.Now;
Noble gases belongs to group 18
Alkali earth metals belongs to group 2
Halogens belongs to group 17
Alkali metals belongs to group 1
Transition metals belongs to group 3-12

Which one of the following is an example of a difficulty caused by thermal
expansion?
O A. The siding on a house buckles on a hot day.
OB. Watery iced tea
OC. Smog in the air during summer heat
OD. lce cream not getting hard
Answer: A
Explanation:just passed it
Answer:
A. The siding on a house buckles on a hot day
Explanation:
The key word in this question is EXPANSION. Without even knowing the siding expands causing it to buckle when it's hot, you can use process of elimination. It can't be answer B because watered down iced tea would most likely be as a result of the ice melting which is the opposite of expanding. It can't be C because air is not solidified and therefore can't expand. Lastly, D cannot be it because ice cream expands when cold, causing it to become hard. If it's not hardening then it's not expanding. This is also the correct answer on a p e.x

Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

Which of the following best represents and explains the formula for a compound made from fluorine and hydrogen?
A. HF, because both fluorine and hydrogen are capable of forming only one ionic bond.
B. HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
C. H2F, because fluorine is short of two electrons, and hydrogen is short of one electron.
D. H2F, because fluorine is capable of forming one, and hydrogen is capable of forming two covalent bonds.
Thank you
The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
Therefore, the correct option is option B.

how many elements and atoms are in marble
Answer:
Explanation:
Scientists know that there are 6x1023 molecules in a mole - so we have about 0.5x1023 molecules in our marble…and since every silicon dioxide molecule has one atom of silicon and two of oxygen, we have a grand total of 1.5x1023 atoms. That's 150,000,000,000,000,000,000,000 atoms
What happens yo temperature in your layer as u you go higher in altitude?
Answer:
Temperatures decrease with increasing height as the ozone layer is left behind and the air thins out with increasing altitude. The lowest portion of the low-pressure mesosphere is heated by the warm air of the upper stratosphere. This heat radiates upward, getting less intense as altitude increases.

What is the potential energy of a 5 kg apple that is sitting on a 1.5 m high
tree branch? GPE=ham
Answer:
PE = 73.58 J
Explanation:
Given data:
Mass of apple = 5 Kg
Height of tree = 1.5 m
Potential energy = ?
Solution:
Formula:
PE = mgh
g = 9.81 m/s
by putting values,
PE = 5 Kg × 9.81 m/s × 1.5 m
PE = 73.58 J (Kgm²/s = J)
What is specific heat? How are the factors affecting it?
Answer:
Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.
Explanation:
by dividing the heat capacity by the quantity of substance in a body, the resulting specific heat capacity is a function of the structure of the substance itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store thermal energy.

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?
- 20 mL
- 259 mL
- 25 mL
- 50 mL
Answer:
The volume in milliliters is 250mL
Explanation:
The volume of a rectangle is obtained using the equation:
Volume = Length * Width * Height
In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:
Volume = 5cm * 5cm * 10cm
Volume = 250cm³
1mL = 1cm³.
That means the volume in milliliters is 250mL
