This statement is false. When water is decomposed into hydrogen and oxygen; these gases are in a position of combining again to reform water. Water is a molecule consisting of one atom of oxygen bound to two hydrogen atoms. The atoms are joined by covalent bonds; however they have addition hydrogen bonds between the partial negative oxygen and the partial positive hydrogen atom.
Answer: C
Explanation: This is because of a nice thing called guessing
Answer:
Option D
Explanation:
A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
A common means of expressing quantities, the values of which may span many orders of magnitude, is to use a logarithmic scale.
The hydroxide ion molarity may be expressed as a p-function, or pOH.
pOH = −log[OH−]
Basic solutions are those with hydronium ion molarities less than 1.0 × 10−7 M and hydroxide ion molarities greater than 1.0 × 10−7 M (corresponding to pH values greater than 7.00 and pOH values less than 7.00).
To convert the given number of moles of aluminum to grams, we need to use the molar mass of the element as the conversion factor. Aluminum has a molar mass of 26.981 g/ mol. The answer to this problem is b. <span>fraction: 26.981 g Al over one mol Al. </span>
Answer:
Vascular plants are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant. Non-vascular plants are plants mostly found in damp and moist areas and lack specialized vascular tissues. Vascular plants are also known as tracheophytes.
