A new material was produced in a laboratory by bonding atoms of
different elements together in a unique arrangement. Other laboratories
were able to reproduce these results, producing the same material with
the same elements in the same arrangement. What type of matter was
produced?
*
Answer:
A compound
Explanation:
A compound is a substance formed from the chemical combination of atoms of two or more elements together.
A chemical compound always contains the same kinds of atoms of elements combined together in as specific ratio by mass and can be represented by a chemical formula. For example, water is a compound formed from the chemical combination of hydrogen and oxygen atoms in the ratio of 2 : 1. It has a chemical formula H2O.
A pure compound also always have the same chemical properties irrespective of the source of the compound. For example, chemically pure has similar properties irrespective of whether it is obtained from rain, streams or underground wells.
Therefore, if a new material was produced in a laboratory by bonding atoms of different elements together in a unique arrangement and other laboratories were able to reproduce these results, producing the same material with the same elements in the same arrangement, then the substance must be a compound.

Answer:
30 N
Explanation:
To find force you multiple mass by acceleration. If you multiple 10kg by 3 m/s you then get 30 N.
Answer:
30 N
Explanation:
Force can be found by multiplying the force by the acceleration.
F=m*a
The mass of the bowling ball is 10 kilograms. The acceleration is 3 meters per second squared.
• m= 10 kg
• a= 3 m/s^2
Substitute the values into the formula.
F= 10 kg * 3 m/s^2
Multiply.
F= 30 kg*m/s^2
• 1 kilogram meter per second squared is equal to 1 Newton.
• Therefore our answer of 30 kg*m/s^2 is equal to 30 Newtons.
F= 30 N
The correct answer is B. 30 Newtons.

Which type of bond will chromium atoms likely to form with other chromium atoms
A:ionic
B:covalent
C:metallic
Answer: B
Explanation: Covalent bonds where electrons are not shared equally between two atoms are called polar covalent bond. As shown above, the electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms.
There are two types of chemical compound one is covalent compound and other is ionic compound in chemistry. The covalent bond will be formed between two chromium atoms. 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 formed by sharing of electron and ionic bond formed by complete transfer of electron.
Element with same electronegativity difference combine together by covalent bond whereas ionic bond is formed by elements whose electronegativity difference is high.
As two chromium is combining that is two two element with same electronegativity is combining therefore, formation of covalent bond is the only possibility.
Therefore covalent bond will be formed between two chromium atoms. the correct option is option B.

4. When the sulfide ion is oxidised to the sulfur atom, the number of
1 point
protons in the nucleus ... increase or decrease
Answer:
increase
Explanation:
Oxidation, in chemistry, refers to when electrons are lost by an atom, hence, making the atom more positively charged. In contrast to this is reduction, which is the acceptance of electrons.
In this case, a sulfide ion (S²-) is said to be oxidized i.e loses electrons, till it becomes a sulfur atom (S). As the oxidation number has increased from -2 to 0, this means that the number of protons has INCREASED.

A: The screw with 9 wraps.
B: The screw with 2 wraps.
C: The screw with 10 wraps.
D: The screw with 6 wraps.
Answer:
The screw with 10 wraps is the correct answer
Explanation:
The screw with 6 wraps would create a strong hold.
What do you mean by screw?The strongest member of the family of wood screws is a lag screw. It is a reliable and sturdy fastener that frequently has a square head or an externally powered hex drive.
In general, lag screws are significantly stronger and heavier than standard wood screws. They have a tapered point and coarse threads.
Thus, The screw with 6 wraps would create a strong hold.

Original sequence
deletion insertion substitution
deletion insertion substitution
deletion insertion substitution
Answer:
A. ✔️Substitution
B. ✔️Insertion
C. ✔️Deletion
Explanation:
In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.
Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.
Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.
In genetics, there are: Substitution, Insertion and Deletion mutations.
Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.
Answer:
A. Substitution
B. Insertion
C. Deletion

Exothermic reactions release energy. Where is the energy used for these reactions to occur stored? .
Answer:
In the chemical bonds.
Explanation:
There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.
Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.

What change occurs to an atom when it forms negative ion
Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ion. Therefore, when an atom forms a negative ion, atom become cation.
What is Ions?Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.
Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. When an atom forms a negative ion, then atom itself gain positive charge over it and become cation by loosing electron.
Therefore, when an atom forms a negative ion, atom become cation.
