Answer:
0.2 moles of CO₂ are produced
Explanation:
Given data:
Moles of CO₂ produced = ?
Moles of Na₂CO₃ react = 0.2 mol
Solution:
Chemical equation:
Na₂CO₃ + 2HCl → 2NaCl + CO₂ + H₂O
Now we will compare the moles of CO₂ with Na₂CO₃ .
Na₂CO₃ : CO₂
1 : 1
0.2 : 0.2
Thus, 0.2 moles of CO₂ are produced.
M=
V=
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance.
To obtain the density of the aluminum, we'll begin by calculating the volume of the aluminum. This can be obtained as follow:
From the question given above, each side of the aluminum cube measures 3 cm. Thus,
Length (L) = 3 cm
Width (W) = 3 cm
Height (H) = 3 cm
Volume = Length × Width × Height
Volume = 3 × 3 × 3
Therefore, the volume of the aluminum is 27 cm³
Finally, we shall determine the density of the aluminum. This can be obtained as follow:
Mass = 81 g
Volume = 27 cm³
Therefore, the density of the aluminum is 3 g/cm³

Answer:
27
Explanation: volume-3 times 6=18 /mass- 81 times 6= 486.... 486 divided by 18 = 27.... a cube has 6 sides.
Answer: 7.07 grams
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require 1 mole of
Thus 0.052 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 1 mole of
Thus 0.052 moles of give = of
Mass of
Thus 7.07 g of will be produced from the given masses of both reactants.
Answer:
There are currently a variety of advanced medical treatment screening programs for certain types of cancer that have resulted in more people having a better chance of healing or living longer.
Explanation:
Exercise helps cancer survivors cope with and recover from treatment; exercise may improve the health of long term cancer survivors and extend survival. Physical exercise will benefit throughout the spectrum of cancer. However, an understanding of the amount, type and intensity of exercise needed has not been fully elucidated. There is sufficient evidence to promote exercise in cancer survivors following careful assessment and tailoring on exercise prescription.
"The field of oncology will benefit from understanding the importance of physical activity both for primary prevention as well as in helping cancer survivors cope with and recover from treatments, improve the health of long term cancer survivors and possibly even reduce the risk of recurrence and extend survival after a cancer diagnosis" (P. Rajarajeswaran, R. Vishnupriya)
Additional studies will be needed to more firmly establish physical activity benefits to cancer survivors.
Exercise is key both in the prevention and treatment of cancer, since it improves the quality and life expectancy of patients.

The benefits of exercise against cancer are innumerable: it helps prevent it, reduces the side effects of chemotherapy and radiotherapy, decreases cancer recurrence, improves vital energy, mobility and balance and reduces fatigue, maintains muscle mass, improves self-esteem and sleep quality, decreases the level of anxiety, depression and stress.
No one doubts the importance of physical activity, exercise and sport in global health, in the prevention and even in the treatment of numerous diseases. Among these diseases is cancer. There are more than 10,000 scientific publications that have studied the links between exercise and cancer and almost all of them with positive results regarding the prevention of numerous types of tumors, the decrease in cancer recurrence and the best prognosis of the latter if You exercise.
It is scientifically proven that properly prescribed physical exercise can be performed without risk during and after chemotherapy and radiotherapy treatments. However, it is necessary to adjust its intensity, duration, weekly frequency and type of exercise to the general condition of the patient. Physical exercise will improve the quality of life, fatigue and mood of the cancer patient being treated. It will also improve the prognosis of the disease, its quality of future life and its final life expectancy.
Research the benefits and risks of exercise and youth.
The benefits of physical activity and sports in young people imply a better physical condition, but also plays a fundamental role from the psychological and social. Every healthy habit is best incorporated from childhood, so that it becomes natural and everyday and improves the quality of life of our future adults.
The benefits of physical activity in youth are several:
Children and young people should perform daily physical activities in the form of commuting, games, recreational activities, physical education, programmed exercises and sports, in the context of school and clubs, if possible integrating other family members.
Answer:
H20
Explanation:
peroxide would also eat bacteria along with the water
The primary intermolecular forces which act between a molecule of hydrogen peroxide (H2O2) and an iron(III) cation (Fe3+) are ion-dipole attractions. These arise due to the polar nature of the H2O2 molecule and the charged state of the Fe3+ ion.
The kind of intermolecular forces that act between a hydrogen peroxide molecule and an iron(III) cation chiefly involve ion-dipole attractions, which are a type of intermolecular force. This occurs due to the polar nature of the hydrogen peroxide molecule (H2O2) and the charged iron(III) ion (Fe3+).
The O-H bonds in the hydrogen peroxide molecule are polar as oxygen exhibits a higher electronegativity than hydrogen, meaning that it has a tendency to draw electrons closer to itself. This results in a dipole with partial negative charge residing at the oxygen end of the molecule, and a partial positive charge at the hydrogen end. Meanwhile, the iron(III) ion has a positive charge. This makes for a strong ion-dipole interaction between the two.
It's important to remember that intermolecular forces are the attractions between molecules which are crucial to their physical properties, while intramolecular forces are those that keep a single molecule intact. Further, although the term 'hydrogen bond' may suggest a bond between hydrogen and other atoms, it is, in fact, an intermolecular attraction force which is stronger than others like dipole-dipole attractions and dispersion forces.
