Acid reflux occurs when acid from a person's stomach escapes from the stomach and enters the esophagus, a flexible tube that leads into the stomach. Which substance would be best for neutralizing stomach acid?
The substance which will be the best for neutralizing stomach acid is Antacid.
What is Antacid ?Antacids are medications that counteract (neutralize) your stomach's acid to ease heartburn and indigestion.
Heartburn, indigestion, and upset stomach can be treated with antacids, which neutralize stomach acid.
Some antacids have been used to treat diarrhea and constipation. Marketed antacids include sodium, calcium, magnesium, or aluminum salts.
They are available without a prescription from pharmacies and stores and come in liquid or chewable tablet form.
Therefore, The substance which will be the best for neutralizing stomach acid is Antacid.

Analyze the given diagram of the carbon cycle below.
An image of carbon cycle is shown. The sun, a cloud, two trees, one towards left and the other towards right, an animal, lake, and a factory are included. Arrow A points from the sun to the left tree. Arrow B points from the air above the clouds to the left tree. Arrow C points from the factory towards the air above the clouds. Arrow D points from the air to the lake labeled Carbonates in Water. Arrow E points from the label Dead Organism under the animal to label Fossils and Fossil Fuels. Arrow F points from the right tree to the air.
Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer. (10 points)
Answer:
Part 1:
Arrow F represents Cellular Respiration, showing how the tree produces carbon after it has finished the process of Cellular Respiration.
Part 2:
Matter is conserved in this image because it shows the process of Photosynthesis and cellular respiration. These are both examples of The Law of Conservation of Mass. During both of these processes, the mass of the reactants is the same as the mass of the products.
Part 3:
This process shows the carbon cycle by showing how carbon transfers to many different types of matter and back again. It shows the process of cellular respiration, which produces carbon using the products of photosynthesis, which uses the carbon produced by cellular respiration. This shows a cycle because each of them depends on the other.

Explanation:
The offsprings' traits depend on which parent the offspring inherited more copies of genes from. agree or disagree
Answer: disagree
Explanation:
The gene traits of offsprings depends on the inheritance from parent. There will be some dominants traits as well as recessive traits from parents. Hence the statement is incorrect.
What is inheritance?Inheritance is the biological process of transferring genes from parents to offsprings. Identical daughter cells are produced through cell division. Cell division carries through methods such as mitosis, meiosis, binary division etc.
The genetic traits from parents inherited to the offsprings sometimes be equal from both parents and called the homozygous. Whereas the if the traits transferred is unequal it is referred to as heterozygous.
The trends in inheritance is studied well by Griger Mental, who proposed the punnett square to predict the pattern of genetic traits inherited from parents. Hence, the genetic traits both quantitative and qualitative traits are dependant upon both parents and the environmental factors.

What is the mass (in grams) of 5.00 L of NH₃ at STP?
Answer:
3.79 grams
Explanation:
22.4= STP volume . Molar mass of NH3=17.031
5.00 NH3 × (1 mol/22.4 L) =0.223
convert to grams->
0.223× 17.031= 3.79
According to ideal gas equation and standard temperature and pressure conditions the mass in grams of ammonia is 0.037 g.
What is ideal gas equation?The ideal gas law is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.
The law can be derived from microscopic kinetic theory .All the other gas laws equations can be derived from ideal gas equation, In the given example at standard temperature and pressure conditions, P=1 atmosphere
V=5 L , molar mass of ammonia=17.031 g/mole,R=8.314 T=273 K
Substituting all these values in ideal gas equation,
mass=PV×molar mass/RT
mass=1×5×17.031/8.314×273=0.037 g
Thus the mass of ammonia gas in grams at STP is 0.037 g.

Which of the following correctly pairs the subatomic particle with its charge? (2 points) Group of answer choices Electron—neutral Electron—positive Neutron—neutral Neutron—positive
Answer: B
Explanation:
protons are positive,
electrons are negative,
and neutrons are neutral.
the amount of electrons to protons is always the same in a balanced atom.
electrons can be removed creating "ions" which is simply an unbalanced atom. removing protons would result in a different type of atom or element.
Answer:
Neutron - neutral

You need to make 10.0 L of 1.2 M KNO3. What molar ( concentration) would the potassium nitrate solution need to be if you were to use only 2.5 L of it? *
Answer:
2.5L [NaCl] concentrate needs to be 4.8 Molar solution before dilution to prep 10L of 1.2M KNO₃ solution.
Explanation:
Generally, moles of solute in solution before dilution must equal moles of solute after dilution.
By definition Molarity = moles solute/volume of solution in Liters
=> moles solute = Molarity x Volume (L)
Apply moles before dilution = moles after dilution ...
=> (Molarity X Volume)before dilution = (Molarity X Volume)after dilution
=> (M)(2.5L)before = (1.2M)(10.0L)after
=> Molarity of 2.5L concentrate = (1.2M)(10.0L)/(2.5L) = 4.8 Molar concentrate
