If you have respiratory or heart problems, _____ can make it worse. carbon monoxide oxygen nitrogen sulfur oxide nitrogen oxide
Answers
If you have respiratory or heart problems, carbon monoxide can make it worse. This is because carbon monoxide is soluble in water and our body consists mostly of water. It can be toxic when dissolved in large amounts.

Alpha particles are less dense than gold atoms.
Answers
According to ErnestRutherford's gold foil tests, the true statement is that space makes up the majority of gold atoms. The correct option is A.
According to Rutherford's studies, the majority of the alphaparticles encountered free space inside the atom since they mostly went through the gold foil with little to no deflection.
This finding helped scientists comprehend that atoms have a small, compact nucleus at their center and are primarily made up of empty space elsewhere in the atom.
The nuclearmodel of the atom was created as a result of the deflection of several alpha particles, which showed that they came into contact with the positively charged atom's nucleus.
Thus, the correct option is A.

Answer:
In polar coordinates, the origin is called the pole.
Explanation:
The position of a point in a polar coordinate system is defined by using the distance from a fixed point and an angle made with a fixed ray from that point. It is a two-dimensional coordinate system.
The polar coordinates is defined as
Where, r is radius and θ is the angle with the polar axis, i.e. positive axis.
In a coordinate system (0,0) is called origin.
In polar coordinate system (0,0) is called pole.
Therefore, in polar coordinates, the origin is called the pole.

Final answer:
The balanced equation for the reaction between nitrogen and hydrogen to form ammonia is N₂(g) + 3H₂(g) --> 2NH3(g). This uses the concept of balanced chemical equations, which ensure the same number of atoms of each element on both sides.
Explanation:
The reactants in the question are hydrogen and nitrogen, and they react to form the product, ammonia. This reaction can be described using a balanced chemical equation, which ensures that the number of atoms of each element are the same on both the reactant and product sides of the equation.
The balanced equation for this reaction is N₂(g) + 3H₂(g) --> 2NH3(g). Here, N₂ represents nitrogen, H₂ represents hydrogen, and NH₃ represents ammonia. The 'g' in brackets indicates that these compounds are in their gaseous states. The numbers in front of the chemical formulas are called stoichiometric coefficients and they indicate the ratio in which the reactants react and the products form. In this case, one nitrogen molecule reacts with three hydrogen molecules to yield two ammonia molecules.
Chemical reactions, including this one, proceed from left to right as shown by the arrow. They show how reactants become products, similar to mathematical equations.

All these compounds are ionic compounds and the formula of the compounds are: Tin(II) chloride - SnCl₂, potassium sulphide- K₂S, calcium chloride - CaCl₂.
What is chemical formula?
The chemical formula of a compound make them easy to identify the elements of composition. The formula of a compound s given with the chemical symbols of elements.
The subscripts of atoms is the number of that elements in the compounds. For instance, tin(II) chloride is formed by losing two electrons from the metal tin -Sn to each two chlorine atoms and thus the formula is SnCl₂.
Potassium sulphide is an ionic compound formed by losing one electrons from potassium to the sulphur atom. Sulphur needs two electrons to attain octet thus it binds with two K atoms and the formula is K₂S.
Calcium chloride is formed by the ionic bonding between calcium and chlorine atom. Calcium has the valency of two thus, it donates two electrons each to each chlorine atoms and hence the formula is CaCl₂.

Answer: Option (B) is the correct answer.
Explanation:
According to Arrhenius, acid are the substance that produce hydrogen ions when dissolved in a solution.
For example, shows that HBr is an Arrhenius acid.
Whereas Arrhenius bases are the substances that produce hydroxide ions when dissolved in a solution.
For example, shows that KOH is an Arrhenius base.
Therefore, when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution then following reaction occurs.
Thus, we can conclude that out of the given options, KBr is the product.
