Answer:
The middle hydrogen is bonded to 2
elements.
Each hydrogen must be bonded to one element which is oxygen
It's something to do with the weathering process.
Eg. At night it's really cold, and in the day it's really hot.
Because the temperature keeps changing dramatically day in and day out,
the sand dunes start to be sort of hacked or re-shaped, or even formed.
Answer:
876 grams
Explanation:
Convert specific gravity to density, using water density 1.0 g/ml
d = e.g x 1.0 g/ml = 1.168 g/ml
d = m/v (mass/volume)
m = dxv = 1.168 g/ml x 750 ml = 876 grams
D.The products will have at least 2 Na atoms and 1 O atom.
<h3>Further explanation
</h3>
Conservation of mass states that
<em>In a closed system, the masses before and after the reaction are the same
</em>
So it can be concluded
- mass of the reactants = mass of the products
- mass cannot be created or destroyed
- The number of atoms involved in a reaction remains the same⇒ number of moles also the same
- chemical equation in balanced form
So the number of atoms in reactants and products remains the same
Because one of the reactants in a reaction is Na₂O, so <em>The products will have at least 2 Na atoms and 1 O atom.</em>
Answer:
destruction of red balloons: hemolysis
shaking hands and feet: parkinson's or cerebellar syndrome
pus streaks in the throat: pharyngitis
Inability of the immune system to fight pathogens: HIV or AIDS
Explanation:
In hemolysis there is a destruction of red balloons, thus generating high levels of jaundice by metabolizing the hemoglobin of those red balloons that were destroyed, generally there are pictures of hepatomegaly or an enlarged spleen.
In Parkynson's disease, there is a degeneration of dopaminergic neuronal cells, which is why there is no synthesis of dopamine. It is for this reason that these patients take levo dopa, the term levo is because a chemical group is added to trap the blood-brain barrier.
As for pharyngitis, it is a bacterial infectious disease that can manifest itself in some cases as purulent collections, inflammation and edema in the pharynx.
And finally, as for the human immunodeficiency syndrome or HIV, it is a symptom that generates a retrovirus, which can remain latent or not, in the event that it does not remain latent and is activated by destroying LTDC4, the disease would be called AIDS. Patients suffering from this disease can manifest deep mycoses, malignant neoplasms (the most frequent is kaposi's sarcoma), opportunistic infections such as pneumonia or meningitis, etc.
